Emily Ratajkowski definitely took Rihanna’s “shine bright like a diamond” advice to heart, arriving at the singer’s annual Diamond Ball in Santa Monica dressed to the nines and ready to twirl like a princess.

The actress arrived on the red carpet in a simple one-shoulder gown with a thigh slit by Rhea Costa. The “Gone Girl” starlet kept the look simple with a pair of Stuart Weitzman “Nudistsong” sandals in nude patent.

Too simple, in our opinion. We’ve seen Emily dressed up and we certainly expected more from her at an event such as the Diamond Ball.
